In the construction of my improved hooppole splitting and shaving machine I employ a frameconsisting of the side pieces 210 and 21 and the end pieces 22 and 23, framing the ends of said side pieces together, and the frame thus constructed is supported by suit able legs 24. The bottom 25 is inserted in the space between the side and end pieces and has an opening 26 formed approximately in its center. A bar 27 has the teeth 28 projecting from its upper surface, thus forming a toothed rack, and said bar is attached to the outer side of the side piece 21 by means of the bolts 29, which bolts pass through the flange 30 and through said side piece. The flan ge 30 projects downwardly from the lower surface and the inner edge of the bar 27. A bar 31 has the teeth 32 projecting from its upper surface and is attached to the outer face of the side piece 2O by means of the bolts 33 passing through the flange 34 and through said side piece 20. The bars 27 and 31 are essentially alike in construction and are mounted in horizontal and transverse alinement with each other, thus forming toothed racks, and said toothed racks are near the rear end of the machine.

The spur-gears 35 and 3G are mounted above the racks 27 and 31, respectively, and with their teeth meshing with the teeth 28 and 32 of said racks, and said spur-gears are connected by being rigidly attached to the shaft `37, and said gears are operated and travel the shaft 37, one upon the outside of each of the bolts and 41, and said collars hold the timber 39 from lateral motion relative to the TOO shaft 37. The timber 39 is slidinglymounted upon the side pieces, and said timber is operated to slide back and forth upon said side pieces by the operation of the handle 38, causing the gears 35 and 36 to travel in the racks. The brackets 44 and 45 are attached to the upper side, of the timber 39, one upon each end of said timber, by means of the woodscrews 46. In the upper ends of the brackets 44 and 45 are horizontal and transversely alined bearings, in which are rotatably mounted the spindles supporting the bar 47.

The bar 47 has an edge 48, which extends forwardly and downwardly from its axis to a point a short distance above the timber 39, and a handle 49 is rigidly fixed to the end of said bar 47, outside of the bearing in the bracket 45, for operating said edge. The bearings 50 and 51 are mounted in horizontal and transverse alinement in the side pieces 20 and 21 a short distance in front of the ends of the racks 27 and 31, and a shaft 52 is mounted in said bearings. Upon the center of the shaft 52 is fixed a spur-gear 53 to be driven by said shaft, and upon the end of the shaft 52, outsideof said side piece 20, is a toothed clutch 54, rigidly fixed to said shaft. The spur-gear 53 operates in the opening 26 of the bottom 25. A driving-pulley is loosely mounted upon the end of the shaft 52 and y carries upon its hub the clutch 56, the teeth of which intermesh with the teeth upon the clutch 54 and drive said clutch, thus driving the shaft 52. The pulley 55 is mounted for lateral motion upon the shaft 52, and the clutches 54 and 56 may be thrown into and out of engagement with each other by operating the pulley 55 sidewise or in any suitable manner.

Mounted upon and fixed to the inner face of the side piece 2O and near the upper edge thereof and above the bottom 25 are the parallel strips 57 and 58, and upon the inner face of the side piece 21 are the parallel strips 59 and 60, the pulleys 61 operating in the space between the strips 57 and 58 and the pulleys 52 opcratin g in the space between the strips 59 and 60, and said pulleys are connected by the bars 63, upon the ends of which said pulleys are rotatably mounted. A toothed rack 64 is mounted upon the bars 63 in a position parallel with the side pieces 2O and 2l and approximately half-way between said side pieces and with its teeth projecting downwardly and meshing with the teeth upon the spur-gear 53, as required to drive said rack 64 backwardly and forwardly by the rotation of the shaft 52.

Attached to the rear end of the toothed vrack 64 is a hook 65, and a retractile coilspring 66 is attached at its front end to said hook. A hook 67 is fixed to the upper edge of the end piece 23, and the rear end of said spring 66 is attached to said hook 67. rlhe tension of the coil-spring 66 is exerted to draw the toothed rack 64 backwardly.

An angle-bar 68 is mounted transversely upon the upper side and at the front end of the toothed rack 64 and is secured in position by means of the bolts or rivets 69 in such a way that one web of said bar occupies a vertical position. The ears 70 an d 7l are formed integral with the ends of the vertical web of the angle-bar 68 and are turned forwardly and upwardly from the upper edge of said web and have horizontal and transverselyalined bearings in their upper ends, in which is pivotally mounted the eccentric 72. The eccentric 72 consists of the cylindrical body, the periphery of which is eccentric to its spindie 73, and the handle 74 is fixed to the outer end of the spindle 73, which is above the side piece 20, for operating said eccentric.

A bracket 75 is mounted upon and xed to the side piece 20 above the shaft 52, and a similar bracket 76 is mounted upon and fixed to the side piece 2l in alinement with said bracket 75. The brackets 75 and 76 are held in position by means of the wood-screws 77. Mounted in bearings in the brackets 75 and 76 and in parallel positions transversely of the machine are the rollers 78, 79, 89, 81, 82, 83, and 84. The rollers 78, 79, 80, 81, and 82 are in the same horizon tal plane, and the rollers 83 and 84 are in a plane slightly above the said rollers 78, 79, 80, 8l, and 82. The rollers 79 and 81 are mounted in bearings 85, which slide up and down in the brackets, and said bearings are normally held up by the coil-springs 86. The rollers 78, 80,82, and 84 are mounted in rigid or fixed bearings in said brackets.

The roller 83 consists of the portions 87, 88, 89, and 90, which are essentially alike and are mountedend to end. Each of the portions comprising the roller 83 consists of the cylinder, having an annular V-shaped groove 91 in its center and spindles projecting from its ends. lach of the portions comprising the roller 83 is mounted to operate independw ently of each of the other portions. The portion which is adjacent the bracket 75 has its outside spindle mounted in the bearing 92, which slides up and down in the bracket 75 and is held normally in position by the expansive coil-sprin g 93. The portion which is adjacent the bracket 76 has its outer spindle mounted in a bearing similar to the bearing 92, and said bearing is held in position by a coil-spring similar to the coil-spring 93. A bar 94 is mounted transversely of the machine and is attached to the brackets 75 and 76, above the bearings 92, by means of the lag-screws 95.

The bearing-hangers 96, 97, and 98 are attached to said bar 94 by means of the lagscrews 99. The hangers 96, 97, and 98 are essentially alike and consist of the frames 100. (Shown in Fig. 15.)

The horizontal upper portion 101 of the frame fits against the under side of the bar 94 and has screw-threaded apertures to rcceive the lag-screws 99. rlhe lower portion 192 of the frame has a semicircular recess IOC IIO

' dovetailed slots cut in its rear end, in which 102 in its upper side, which recess forms the lower half of the bearing, and the portions 101 and 102 are connected by the vertical portions 103 and 104. The spindles which operate in the recess in the upper face of the portion 102 are less than one-half as long as the recess. In other words, the spindle on the inner end of the portion 87 of the roller extends into and operates within one end of said recess 102iL of the hanger 96, and the spindle on the rear end of the portion 88 of the roller extends into and operates within the end of said recess 102, opposite the end in which the other spindle operates. In the same way the meeting ends of the spindles on the portions 88 and 89 operate in the hanger 97, and the meeting ends of the spindles upon the portions 88 and 89 operate in the recess 102"L of the hanger 97, and the meeting ends ofthe spindle upon the portions 89 and 90 operate in the hanger 98. Above the spindle on the inner end of the portion 87 is a plate 105, having a semicircular recess in its lower face and forming the upper half of a bearing for said spindle, and a coil-spring 106 is interposed between said plate and the horizontal portion 101 of the frame, thus giving a yieldin downward pressure to the spindle. A plate 107, similar to the plate 105, is placed above the spindle on the rear end of the portion 88, and a coil-spring 108, similar to the spring 106, is placed upon said plate. Each of the hangers 96, 97, and 98 is provided with the plates 105 and 107 and the springs 106 and 108, thus forming two yielding bearings in each hanger.

Between the rollers 83 and 84 is mounted a knife 109, with its edge directly back of the lower part of the roller 83. The knife 109 is mounted with its ends in slots formed upon the inner faces of the brackets 75 and 76 and is held adj ustably in position in said slots by means of the wedges 110 and 111. By changing the position of the wedges the edge of the knife may be raised and lowered and its angle may be changed, as desired.

A knife 112, similar in every respect to the knife 109, is mounted behind the roller 84, and said knife is held adjustably in position by means of the wedges 113 and 114. The edge of the knife 112 is somewhat lower than the edge of the knife 109.

The hoop-pole splitters 115 are mounted horizontally in the end piece 22 and above the bottom 25 and in position parallel of the niachine. The splitters 115 each consists of a hollow cylinder 116, and said cylinder has dovetailed slots are mounted the knives 117, 118, and 119. The knife 117 is somewhat longer than the diameter of the cylinder 116 and extends entirely across the rear end of said cylinder and iits tightly within the dovetailed slots within said rear end. The knives used in constructing the splitters are driven endwiseinto the dovetailed slots. 1n the center of the knife 1 17 and projecting backwardly from its edge is a point 120, designed to follow the pith of the hoop-pole. An opening 121 is formed through the knife 117 near its thick edge and directly in front of the point 120. The inner end edges 122 of the knives 118 and 119 are beveled to fit the beveled side faces of the knife 117, and pins 123 project from said end edges into the opening 121. The knives 118 and 119 only extend to opposite sides of the knife 117, and the inner ends of said knives 118 and 119 are supported by the pins 123, engaging in the opening 121. The splitting devices thus constructed, and as shown in Fig. 8, will split a hoop-pole into four pieces. On the same principle the `device may be constructed, as shown in Fig. 11, to split a hoop-pole into six pieces, or it may be so constructed as to split a hoop-pole into three pieces or into any other desired number of pieces.

In the operation of my improved hoop-pole splitting and shaving machine the hoop-poles are laid uponthe bottom 25 in front of the toothed rack 64 and one hoop-pole is placed in each of the splitters 115, with the point 120 in itsheart or pith. Before beingplaced upon the point 120 it is better to cut the end of the hoop-pole square off with a saw or in any other suitable way. The bar 124 is attached to the front endl of the toothed rack 64 and extends entirely across the bottom 25 and inside of the side pieces 20 and 21. After the hoop-poles have been placed in position with their front ends in the splitters 115 the operator throws the belt-wheel 55 over until the clutch connects said belt-wheel and the shaft 52, and then the toothed rack 64 is driven forwardly by the spur-gear 53, thus carrying the bar '124 forwardly against the butt-ends of the hooppoles and pushing said hoop-poles through the splitters 115. Then the bar 124' has been car- IOO riednearly to the knives upon the splitters 115,

the belt-wheel 55 is thrown back, thus disconnecting the clutch from the shaft, and th ecoilspring 66 withdraws the toothed rack 64 to its normal position. The hoop-poles which have been thus split into four or six pieces are then carried to the rear end of the machine and are placed under the edge 48 and upon the timber 39, with their front ends resting upon the roller 78. They are then pushed forwardly until their front ends pass under the roller 83. In placing the pieces in position upon the timber 39 the bark side is placed downwardly and the heart edge is placed in the grooves 91. Then the operator engages the handle 49 and presses it forwardly, thus depressing the edge 48 of the bar 47 into the edge of the hoop-pole. The operator then engages the handle 38 and swings upwardly and forwardly, thus causing the gears 35 and 36 to travel forwardly in the toothed racks 27 and 31 and sliding the timber 39 forwardly upon the side pieces 20 and 21. As the timber slides forwardly the pieces of hoop-poles are pushed between the roller 79 and the knife 109, and a portion of the heart 0f the IIO stick is cut away by said knife, approximately as indicated by the line a in Fig. 13. rlhe front end of the hoop-pole then passes under the roller Si, over the roller 81, and another shaving is taken from the heart side of the stick, cutting it approximately to the line b in Fig. 13. The finished end of the stick then passes over the roller 82 and over the upper edge of the vert-ical web of the angle-bar 68 and under the eccentric 72. The operator then engages the handle 74, operating the eccentric 72, and presses it forwardly, thus pinching the stick between said eccentric and the upper end of said angle-bar. The operator then throws the machine into gear by moving the belt-wheel 55 upon the shaft 52. The toothed rack 64 is then driven forwardly by the operation of the shaft 52, and the hoops are drawn through the machine by the eccentric 72 engaging the an gle-bar 68. After the hoop has been drawn out of the machine the operator throws the machine out of gear, the spring 66 withdraws the toothed rack G4, and the operator swings the lever 38 backwardly and the machine is ready to repeat the operation just described. hoop-poles in the splitters 115 and by placing the split pieces of said hoop-poles upon the timber 39 both at the same time the machine splits and shaves simultaneously. In shaving the hoops, if the knife strikes a knot the roller 79 or 8l, as the case may be, will give, and thus prevent the machine from clogging and breaking the hoops.
